1 '0 all whom 2'6 may concern:

Be it known that I, CLAUDE M. EDWARns, a citizen of the United States of America, residing at Galveston, in the county of Galveston andState of Texas, have invented new and useful Improvements in Telegraph Apparatus, of which the following is especitication.

This invention relates to improvements in telegraph apparatus and has particularapplication to a recording mechanism whereby a tape may be acted upon in such manner that when applied to the sender of a selective telegraph system positive or plus and minus or negative impulses may be directed into the selective receiving apparatus of such systei'n, and is designed for use in conjunction with the systems or apparatus disclosed in my copending applications filed April 9, 1912 and September 6, 1912 and bearing Serial Numbers 689,460 and 718,836 res 'iectively.

Ill carrying-1nd the present invention, it is my purpose to provide a recording apparatus whereby a permanent recordmay be made from a typewriter or the like machine and said record applied to the telegraph sending instrument or transmitter of :1V selective telegraph system whereby the selective receiving apparatus of such system may be actuated in the desired manner.

It is also my purpose to provide a telegraph apparatus wherein by means of arecording mechanism and an actuating mechanism operable from a typewriter in the Writing operation for operating the recorder mechanism, a tape may be punched in such manner that when applied: to the sender or transmitter of a selective-telegrsph system, positive and minus impulses Will'be sent over the'line to the receiving apparatus, the

perforationsdn the tape representing the va rious impulses being arranged in groups.

With the-'above'and other objects in view, the invention consists in the construction combination and arrangement;- of parts-hereinverter seti'o'r'th in and falling within the scope of the claims. I p

In the accompanying drawings: Figure 1 is a side elevation of the recordin 'mech-- anistm Fig. 2 is aside elevation of t e actusting mechanism. operable from the writing lreys of a typewriter for operating the re corder mechanism. Fig. 3'15 '3 similar view of the actuating mechanism operable from the shift keys of the typewriter for 050mb ing the recording mechanism. Fig. 4 is a top plan view of the recorder mechanism, and Fig. 5 is a diagrammatic view of the recorder mechanism.

In the present instance, my recording mechanism is designed to be operated from the keys of a typewriter and embraces an electrically actuatedmechanism operable in the manipulation of the typewriter keys for Writing purposes-to reproduce the matter Written upon the typewriter upon a ribbon or tape, so that apermanent record may be made upon the tape whereby, in the application of the tape to the transmitter of aselective telegraph system, the matter writ ten upon the typewriter may be reproduced at the receiving end of the system for the desired purpose.

In the embodiment of my invention selected for illustrative purposes, the recording apparatus, illustrated in detail in Figs. 1 and 4 of the drawings, includes a suitable base 1, upstanding from which adjacent to the opposite ends thereof are supporting posts 2 carrying at their upper ends a telel-i'sm with the base 1. Suitably secured to the upper and lower surfaces of the plate 3 adjacent to one end thereof and disposed in parallel vertical planes are magnets 4 and 5 respectively, each controlling an armature secured to a lever 6'pivoted adjacent to its free end as at 7 'upon a post 8 and carrying between the post and the respective magnet a die or punch 9 movable through a suitable guide if desired and adapted to enter an opening 10 in the die plate 3.

The punches or dies 9', 9 are disposed the relatively opposite sides of the respecranged at the opposite sides of the longitudinal center' line of the die plate 3', the openings 10 cooperating with the punches or dies 9 being similarly located so that in the operation of the punches or dies under the action of the magnets, a tape or ribbon will-be perforated adjacent to its opposite side edges. Suitable tension devices are employed tohold' the levers 6, 6 in normal or carried thereby will be normally spaced spurt from the poles of the respective magnets. In th'e present instance, each tension device is com spring 11 having one end suitably secured l is an minding: screw 12 disposed within a,

male die or punch plate 3 arranged in paraltive levers 6, 6 and as a consequence are ar-' inoperative positions so that the armatures sed of a coiled contractile 1&0

lug 13 carried by the respective post 8, and the opposite'end fastened to the respective lever 6 beyond the pivot 7 thereof. Atthe free end of each post 8 is an appropriate form of bracket 14 equipped at one end and to one side of the respective post with an adjusting screw 15 whereby the movement of the respective lever 6 may be controlled, and at its opposite end'on the other side of the post with a co'ntact screw 16 adapted to be engaged by a contact 17 carried by the adjacent end of the respective lever 6. Also mounted upon the upper surface of the die plate 3 and suitably secured thereto and at an appropriate distance from the magnet 4 is a magnet 18 having disposed within the influence thereof an armature carried by a lever 19 pivoted adjacent to one end as at 20 upon a post 21 and carrying between the post 21 and magnet 18, a die or punch'22 movable within a suitable guide and cooperating with an opening 23 formed in the die plate immediately below the adjacent end, of the punch or die. This punch or die 22 and its cooperating opening 23 are located in a plane approximately centrally of; the die plate and between the dies 9, 9 controlled by the magnets 4, 5 so that a center row of perforations may be punched into a tape or ribbon whereby said tape may be fed through the transmitter of the telegraph system for sending purposes. To the upper end of the post 21 a bracket 24 is fastened and carries at one end an adjusting screw 25 controlling the movement of the level" 19 about its pivot 20, While the opposite end ofsuch bracket carries an adjusting screw 26 disposed in the path of movement of the free end of the lever 19 and controllingthe movement of such lever under the action of the magnet 18,-whe'n the latter is energized. An appropriate tension device is utilized to hold the lever 19 in normal position, suchdevice, in this case, comprising a coiled contractile spring 27 having one end thereof fastened to the respective end of the lever 19 and-theopposite end secured to an adjusting screw 28/carried by a lug 29-011 the host 21. I

At a point behind the free end of the lever 19 are brackets 30, 3O suitably secured to the upper surface of the (lie plate 3 and spaced apart in parallel relation and provided with alining bearings rotatably holding the shaft 31 upon whishis journaled, between the brackets, a drum 32 plOVltiOtl upon its periphery with radially disposed pins 3? and equipped at one :side with a ratchet wheel 34 the teeth of which are engaged by a spring actuated pawl 35 carried upon the free end of the lever 19 and at all times in engagement with theieeth of the ratchet wheel. hi -the pfesen t instance, a guide plate "3W is "fastened to the irpgpnr surf ace o f-t tre dic 'p'la tc 3 and is ggxroxiiled with a slot through which the pins 33 on the drum 32 work.- Bearing upon the upper surface of the die plate adjacent to the opposite ends thereof are suitable tension rollers 37, 37 while mounted upon the base 1 of the recording mechanism adjacent towhat may be termed the forward end thereof is a tape carrying reel 38, and at the rear end thereof a tape take-up reel 39, the latter being rotatedthrough a suitable belt and pulley device 40 operated from the shaft 31 of the drum 32. The drum 32 constitutes the feeding device of the recording mechanism and the teeth 33 thereon are designed to engage the center row of perforations formed in the tape by the die 19 so as to feed such tape longitudinally of the die plate from the reel 38 onto the reel 39, as

will more fully hereinafter appear.

, Each type bar operating key of a typewriting machine is equipped with an actuating mechanism through the medium of which the magnets 4 and 5 may be. energized to punch the tape in accordance with the letter or character controlled by the key so that when the tape is applied to the sending apparatus or transmitter of a selective telegraph system, the receiving apparatus of such system wlll be actuated in ac-- cordance wit-h the letters or characters represented by the perforations inthe tape. In the drawings, only one key is of a typewriter is shown, such being thought sufficient for the purpose of illustration, and depending common conductor 50 including a source of I energy as a battery 51 for lnstance and grounded as at 52. Extending across the groove 43 at the relatively opposite sides of the apices of such groove are guide springs 53, 53. The keyk, which'is a type bar cont-rolling key, is shown to be in its normal or inactive osition, and in this position of the key t eblock 42 rests within the groove 43 at the upper extremity there of. i In the downward movement of the key, the b1 ck 42 travelsdownwardly in one side of the groove and upon reaching-the lower end (if said side pgstsstheguidespring 53, which yields or gives for this purpose and enters the opposite side of the groove, the guide spring at this end of the groove causin; the block to travel in the opposite side thereof.

The perforations eujacent to one side edge of the tape represent plus impulses, while those adjacent to the opposite side edge represent minus impulses. e. will; assume, for the purpose of ilhlstration, that. l the three blocks 1'? toward the upper end I of the groove 43 are adapted to produce plus impulses and are connected to the Wire 48, and the two remaining blocks connected to the wire or ci'incluctor 49 produce iioinus impulses, three plus and two minus ini- ,7 :7 x

Thus; tluee plus impulses are; recorded one side of the tape and two minus impulses at the opposite side of the tape, the pcrforstions, indicating the irns, being arranged one behind the other owzrg to the tape traveling longitudinally of the lame hem-ti, as will presently appear. it will he unilirstood, of course, that. the -47 of each type her manipulating I-w ore Oiii1C" (l in multiple or parallel the respcctii etuieiuctors 48, 19 so that magnets 4, 5 zty he operated from each l-zey of the typewriter in accordance with the snout o the bloc s 47 j 'gize the magnet 18\ ea.ch one one or the other of the magnets 1, 5 s energized, so thzztv the feeding device will operatetl to move. the tape longitudinally of the die plate for the purpose of disposblock such groove are a in; the perforations in the tape one be hind he other to perforate the tape ennui hy meins of the punch 22, said ltif, connecterl in a circuit cointfii of e ecutluctm S t having one of its so ho u'muecteil to the c ntact l6 and ante kennel as are a pa r o 1 I r. inst- .iuti ed contuctl be seen that when either one of the magnets 4, 5 is energized, the circuit will he closed to the magnet. 18 to energize the hitter and so swing the lever! 19 shout-its pi ot :20 aetuute the punch 591m the arm 58 to close 22 to form a. center hole in the tape. Upon the zleenergization of the magnet 18, the tension device 27 acts to restore the lever to its normal position and advance the drum 3? of the feeding device, incident to the pawl engaging the teeth on the ratchetwheel 34. By means of this construction, it will be seen thatthejupe or strip is fed longitudinally in a step by step manner and remains stationary While the punches 9 9 and are operating.

Erich shift key of the typewriter is also adapted to actuate the magnets 4, 5 for the purpose of perforating the tape to indicate capital letters and figures when the respective shift. keys are depressed for this purpose. The return of the shift keys to their normal positions also actuates the magnets 4,5 to perforate the tape so that the receiving apparatus of the selective telegraph systom may be actuated in such manner as to facilitate thereceiving of small letters. For these purposes the left shift key of the typewriter is used only for figures, While the right shift key is used for capital letters or conv ely, desired. In Fig. 3 of the drawings, 1 have shown only one shift key and as each shift key is equipped with a similar mechanism, itis thought that a disclosure of one Will sufiice for both. -T0 accomplish the aforementioned results, each shift key as s is provided with an upwardly extending arm 58 carrying at its free end a 59 isposed within and adapted to ride around an elliptical groove 60 formed in the plate 67 fixed to a suitable part, of the typewriter frzime in proximity to each shift key. A conductor 61 has one terminal thereof se cured to the block 59 and the free terminal grounded as at (3. Suitebly fastencd to the outer Wall of the groove 60 at each side of plurality of contact blocks 63, 64, five blocks being shown in each group in the present case, To the end and centerb ocks of the group 63 is Wired the positive eontluctor 48, While to the remaining blocks of such group is Wired the negative conductor 49. On the other hand, to the two topmost him-ks of the group ($4 is Wired the negative conductor 49, while to the reinaur ing blocks of this group is Wired the condu tor the guide across the 7 springs 53, extending he groove 60 substantially as and for .rhciore set: forth with rethe actuating mechanism controlled iv her nizn'zinuluting keys The "n to in it. normui ini; sm-h p sition of the c .7 i Within the groove 50 at the upper extra-en y thereof and travels downwardly in one side of the groove upon the depression of the shift key. In the downward movement of the shift key, the group of blocks 63 are bridged by thezblock t e circuit to the &

magnets 4 and 5 so as to perforate the tape to indicate that the following letters are capitals. Upon the release of the 'Slllfl) key, the block 59 travels upwardly and in i the purpose of illustration and it will be understood that the blocks of each group may be arranged in any desired relative positions and in different positions from the blocks of remaining groups, so that the magnets of the punches will be operated properly to punch the tape.

From the foregoing description taken in connection with the accompanying drawings, the construction and mode of operation of my invention will be readily apparent. It will be seen .that each key of the typewriter causes the energization of the magnets controlling the impulse punching dies in a manner difi'erent from the remaining keys so that the tape is punched in such manner that, when applied to the sender of the telegraph system, successive groups of impulses representing various letters, characters and'figures are sent over the line and to the selected point.

In my copending applications hereinbefore referred to, I employ a selective tele graph system including a series of actuating devicesand means whereby an electric current may be directed to any predetermined or selected actuating device. Each actuating device is in the'form of a circuit closer and each of certain of said devices controls a local circuit in which is arranged a group of operating devices. These operating devices are for the purpose of operating the keys upon the key board of a linotype ma.- chine and each group embodies three of such operating devices, owing to the key board of a linotype machine being divided into three banks of keys, one bank being the capital letters, while the two remaining banks embrace the small letters and figures and other symbols respectively. In order that only one of the roup of operating devices controlled by fie energized actuating device will operate at a time so that the desired key on't-he key board of a linotype machine may be depressed, a master .or hex selector is employed and is under the CO1:- trol of certain of the remaining actuating devices. Thus, should it be desired to print a-capital letter, certain impulses will be sent I tape will be punched ing said through the selecting means of the receiving apparatus to actuate the particular actuating device and so close the respective local circuit to the key selector'thereby causing the latter to operate as desired. The impulses representing the capital letters are now sent through the selecting means of the system to the respective actuating device to close the local circuit controlling this particular group of manipulating devices, one of such devices controlling the A in the bank of capital letters. while the two remaining devices control the a in the bank of small ,letters and the numeral 1 in the other bank, respectively, for instance. But, as the master selector has been actuated to capital letter position, the operating device controlling the A will be operated, while the remaining devices remain inactive. From this, the reason for perforating the tape to indicate capital letters, small letters and figures, will be readily apparent.

\Vhile I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myselfftd. the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
